It's rare to see breadboard friendly I2C sensors, but this TO-220 package with 5 pins is, in fact, such a thing! It's a basic temperature sensor, not the highest precision in the world, only ±2°C but it will get the job done when you need simple temperature logging or monitoring.

Wiring it up is easy, pin 2 is SDA, middle pin is GND, pin 4 is SCL and the rightmost pin 5 is VDD. You can power it with 3.3 or 5V logic so it's good for any microcontroller or microcomputer. Note you will need to add I2C pull-ups on your breadboard especially if your I2C controller does not have them built in already
